The ride-hailing company has been trying to expand its food-delivery business to compensate for the collapse of its main business.
Uber has made a takeover offer to buy Postmates, the upstart delivery service, according to three people familiar with the matter, as the on-demand food delivery market consolidates and Uber looks for new ways to make money.
The two companies could reach a deal as early as Monday evening, according to the people, who spoke on the condition of anonymity because they were not authorized to do so publicly. The talks are still going on, the people cautioned, and any potential for a deal could fall apart.
Representatives of Uber and Postmates declined to comment on any potential deal talks.
